    What are these wires with fusible links next to the starter solenoid?

    Curious what these wires do so I can better understand the electrical system.

    The black one with the connector should mate with it's matching male side and connect to the chassis (fenderwell) at a point between the battery and the starter solenoid. It is a MAJOR ground point for a bunch of circuits. The yellow is an important power pickup point that should be on the +12V battery side of the starter solenoid. I think the red/wht with the 90 degree slip-on is the starter solenoid "start" circuit. It looks like this car is missing it's starter solenoid and all of the wiring that connects to it is just hanging in the breeze.

    The starter solenoid may be there - it's out of view. Placed on the inner fender between the washer bottle filler and the front of the shock tower.

    Ok I've gotten it figured out, thanks for the help! The diagrams are a great source of reference. I have the starter solenoid wired correctly and the motor cranks but the fuel pump doesnt prime. I pulled the relay form under the drivers seat and its rusted out so ill be replacing that this afternoon. The other issue im having is even jumping the relay connection the fuel pump still does not have power. There is a wire on my new harness labeled inertia -> FP that the instructions tell me to connect to the power wire to the pump and my understanding is the power wire to the pump is the pink wire with black hash marks? I know the pump is good because I connected it to a power source when I pulled the tank, and my ignition switch is brand new.

    You did check your inertia switch right?
